One type ma l of such a vacuum-jar is shown in Figs. 7 and 9 of the drawings, wherein 1 designates an inclined shoulder on the neck of the jar; 2, an annular groove; 3, the gasket in the groove;

' 4, the screw-threaded end portion of the neck,

and the cap having the flange extending down and over the gasket. AIt is to be underf l the form ot' a solid cylindrical ring, as plainly shown in Fig. 6. Extendingin opposite direction from this ring are the projections M and M'. Secured to the projection M is a handle M". The central portion of the' mold is provided with a central opening C', and eX- tending downwardly from this opening is the annular screw-threaded flange C". Theneckmold sets on the pressing and blowingmold j in the same manner, so a description of one will suiice for both. Referring to Fig. 7, it

will he seen that the blowing-mold is `provided with an upwardly-extending annular rflange 0', which surrounds the flange C" on the neck-mold, and that the bottom of the ilange C" will rest upon a shoulder `C"'' on the blowing-mold. By this construction a tight and solid bearing is provided for the` neck-mold.

F designates the pressing-head or plunger, and F' the cylinderifor operating the plun ger, which is controlled ,by the lever F", fully 4described in the prior patents before Amentioned. Surrounding the plunger arey two plates T and T. The upper plate, T is rigidly secured to the plunger-rod, andthe lower plate T' is slidingly secured thereon and sep cured to the upper plate by means of the bolts K, which extend up throughapertures in the upper plate. Theboltsare provided with nuts K above the plate T for limiting the downward movement of the plate T'. The bolts are surrounded with coiled springs K" for normally holding the plateT in a downward position and exert a yielding pressurel on the plate when the plunger is in operation. Thus far the plungerhead mechanismis the saine asis shown in the prior patents above mentioned. y

G designates the lifting-hooks. In the prior construction these hooks were hinged directly to the upper plate. rience that in some instances the glass will have atendency to stick in the pressingthe ware.

mold, sometimes in one place andsometimes iny another, and the hooks being hinged to ra` rigid plate will be obliged to rise simulta` neously, and thereby tear the glass where stuck in the mold andinj uring the quality of To obviate this diiiiculty, I now I have found by expe` hinge these hooks to a balancing rod O. These hooks are secured to the opposite end of this rod by means of the nuts O', as plainly shown in Figs. 3, 4, and 5. The central portion of' this rod is enlarged, as shown at O", Fig. 5, so as to embrace theupper end of the plunger-rod. This enlarged central portion is provided with an aperture somewhat larger than the rod, 'as also plainly shown in said figure. 0nv opposite sides of this central opening the bar is provided with a depending lug P, which rests upon the top of the plate F. These lugs are located at the exact longitudinal center of the bar, so thatthe bar is normally balanced thereon, as plainly shown in Fig.r 1. With this construction when the neck mold is in position on the pressingmold, as shown in Fig. 1,and the pressing head is lowered, the hooks will engage the oppositely-extending projectionsM M of the neck-mold. The hooks being hinged on the end of the bar and being provided with the Aportion f will be forced. away from the projections M M until the hooks are below these projections, when they will by their own weight fall by gravity and engage these projections. Now when the pressing-head carrying the hooks is raised if any glass sticks at a point in the pressing-mold the bar O will rock or teeter on the lug P and compensate for the irregular pull on the hooks, so that when the glass is finally disengaged from the pressing.- mold the pull will have beeneven at all points on the glass removed, thereby preventing any:injury to the finished ware. To prevent the bar from having too much of a toeter, I provide clips R, which extend over the opposite ends of the bar.

These clips are secured to the top of the plate by means of the bolts R. To prevent the hooks having too much swing when engaging the projections on the neck-mold,- I provide the guards S, secured to the lower plate F". These guards are secured to the plate by means of the bolts S.

The operation of the machine is similar to that shown and described in the prior patents above mentioned. The glass is irst dropped from the gatherer into the pressing-mold D. The plunger is then lowered, so thaty the hookswill engage the projections on the neckmold,- the plunger raised, andthe neck-mold,- with, the depending' glass, removed from the hooks by grasping the yhandle ot' the same and depositedin theblowng-inold. When this is accomplished, the blowing-head (not shown) blows the ware to its completed state. After this is accomplished the blowing mold is opened by means of the handles thereon and the completed ware removed therefrom, with the neck-mold still attached, and placed to one side. To remove the neck-mold, it is simply .unscrewedfrom'the neck of the jar. As constructed it is onlynecessary to give the necknlold a quarter-turn to release it from the j neck, when it is again placed on the pressingmold ready for a new supply of glass. By

IOO

this operation of unscrewing the neck-mold from the neck of the jar instead of opening the neck-mold, as before, the pull or strain will be equal entirely around the neck and the neck will be left perfectly round and without any defects.

I am aware that many minor changes can' be made in the construction and arrangements of parts without in the least departing from the nature and principles of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination in a glass-blowing apparatus, of integral pressing-molds, blowingmolds, and a pressing-header plunger, an integral cylindrical neck-mold provided with a central screw-threaded opening, and oppositely-extending projections, a handle extending from one of the projections, means adapted to engage the projections on the neck-mold and lift the same from the pressing-molds, and mechanism for operating said lifting means.

2. In a glass-blowing machine, the combination `with a pressing-mold, a neck-mold, -a plunger arranged above the pressing-mold, a

on the plate, hooks pivoted to the opposite ends of the rod adapted to engage and lift the neck-mold and means for actuating the plunger.
